BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention generally relates to an improved structure for asport board, more particularly to a sport board structure which isassembled by a hardened layer and a special assembling method.

2. Description of the Prior Art

Water sports are always attractive, especially the earth temperature isincreasing gradually. Taiwan in the subtropical zone is now approaching37-38° C. in summer in the recent years, and Europe and North Americaare sometimes more than 40° C. So that, water sports are more popularthan ever, more particularly to the sea sports.

Although the sea sports in summer are more year and year, surfing ineither Europe or North America is popular all the year as well,therefore the sea sports may not be disappeared due to cold weather.Additionally, following the conditions of water sports in inland lakesand sea activities being increased, the safety to water sport devices orlifesaving devices is relatively promoted.

Snowboard and turfski, applied on the land, are more and more;additionally, such sports may not be limited by that of going to beachesor places close to inland lakes, so that the sports on the land areeasily accepted by customers. On the contrary, a medium where thesnowboard or turfski is on is much harder than water, the safety is moreimportant relatively, wherein the medium can be a snow field or a grass.

With references to FIG. 1 and FIG. 2, which illustrate a schematicexploded view of a structure for a sport board in prior arts and aschematic complete sectional view of the structure for the sport boardin prior arts. As shown in the two figures, a sport board 5 includes afirst layer 51, a second layer 52 and a third layer 53; wherein thefirst layer 51 and third layer 53 are made of low density foammaterials, the second layer 52 is made of high density foam materials.

On the other hand, a method for assembling the structure for the sportboard includes the steps of: (1) pressing and gluing the first layer 51,second layer 52 and third layer 53 by hands; (2) keeping pressing for aperiod of time, and waiting for concreting; (3) machining glue residues;(4) grinding tiny residues; and (5) sticking waterproof rims for waterleaking into the layers.

As a conclusion based on aforesaid method, there are three shortcomingslisted below:

-   (1) The steps of pressing and gluing by hands and keeping pressing    for a period of time are obviously increasing manufacturing cost,    and the effect of gluing may not be good as well.-   (2) Machining and grinding may cost a lot.-   (3) The waterproof rims may be easily leaking water so as to cause    low durability and liability.

Another point, when leaking is happening, the whole structure will becollapsed due to that of a foam material. Hence any one who is playingin the sea or engaging in the work of lifesaving needs to be verycareful for being possibly in a risk.

Therefore, how to figure out such shortcomings is an important issue tothe people who are skilled in the art.

SUMMARY OF THE INVENTION

A method for assembling the improved structure for the sport boardcomprises the steps of: (1) disposing the first layer into a firstsemi-mold of a mold and the third layer into a second semi-mold of themold; (2) preheating the first layer and third layer; (3) locating thesecond layer in between the first layer and third layer and closing themold; (4) assembling the first layer, second layer and third layer; and(5) the cover layer completely wrapping around the first layer, secondlayer and third layer after assembling.
